  1. 1. Influence of water conditions on growth and mineral nutrient uptake of native plants on clacareous soil

    Detta är en avhandling från Aparna Misra, Department of Ecology, Plant Ecology and Systematics, Lund University, Sweden

    Författare :Aparna Misra; Lund University.; Lunds universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; agricultural hydrology; Lantbrukshydrologi; marklära; Växtekologi; Plant ecology; wet growing; wet dry cycles; soil solution; soil moisture; pH; nutrient poor soil; mineral nutrients; dry growing; Bicarbonate; calicole; Soil Science;

    Sammanfattning : The studies presented in Papers I to IV illustrate the importance of soil moisture in soil solution chemistry and response of native plants to the changes induced by change in moisture regime. With the help of glasshouse experiments I tried to study the influence of different treatments of soil moisture conditions on the mineral uptake by native plants of calcareous soil. LÄS MER

  2. 2. Models for Wet Scrubbing of SO2 and NOx

    Detta är en avhandling från Chemical Engineering 2, Lund University

    Författare :Charlotte Brogren; Lund University.; Lunds universitet.; [1997]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; limestone scrubbing; wet scrubbing; absorption; WFGD; flue gases; SO2; mass transfer; NOx; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Sammanfattning : Combustion of fossil fuels is the main source for emissions of sulfur dioxide and nitrogen oxides. Emission regulations and the growing environmental awareness will make great demands upon cost-effective deSO2 and deNOx techniques in the future. LÄS MER

  3. 3. Interception and storage of wet deposited radionuclides in crops

    Detta är en avhandling från Chemical Engineering 2, Lund University

    Författare :Stefan Bengtsson; Sveriges lantbruksuniversitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The emission of radionuclides into the atmosphere from various sources, such as nuclear power plant accidents and nuclear bomb explosions, can result in the interception and uptake of radionuclides by crops in the agricultural ecosystem. These radionuclides e.g. LÄS MER

  4. 4. Land-atmosphere exchange of carbon in a high-Arctic wet tundra ecosystem

    Detta är en avhandling från Lunds universitets geografiska institution

    Författare :Torbern Tagesson; Lund University.; Lunds universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbon; methane; carbon dioxide; climate change; Arctic; NDVI; NDWI; micrometeorology; remote sensing; chamber; tundra;

    Sammanfattning : Arctic ecosystems play a key role in the terrestrial carbon (C) cycle, but spa-tially explicit data on the C exchange is scarce in these remote areas. The global warming is especially dominant in the Arctic, and these areas are vul-nerable to climate change. LÄS MER

  5. 5. Biodegradable nanocomposite films based on amylopectin and chitosan

    Detta är en avhandling från Stockholm : KTH

    Författare :David Nordqvist; KTH.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry Organic chemistry Polymer chemistry; NATURVETENSKAP Kemi Organisk kemi Polymerkemi;

    Sammanfattning : The use of disposable material is rapidly increasing, today the absolute majority of the material used for these application, i.e. food packages, are oil-based plastics such as polyethylene and polypropylene. Therefore it is of great importance to find alternative biodegradable materials made from renewable resources for this huge growing market. LÄS MER
